Appiieation Februaryve, 194s, serial 1510.475353 11 claims. ,(91. sof- 102) This invention` relates to a tool for pipe-fitting and like purposes. More particularly it aims to provide a` compound tool presentingv in theorie coordinated unit means for threading pipe and the 'like combined with pipe cutter means, the latter also in accordance' with the invention involving simpliiied and otherwise improvedv means whereby the tool may readily be utilized either as a single-disk or as a plural-disk cutter selectively.

In the drawing illustrating by way of example one embodiment of the invention z Fig.V 1 isV an elevation o the tool as. a whole, viewing its disk cutter face or side; I

Fig. 2 is a corresponding view,` at right angles to Fig. 1, with parts in longitudinal or vertical section as on the line 2 2 of Fig,- 1;

Fig. 3v is a detail sectional View of the disk and roll cage or holder; y y

Figs. 4 and 5l are cross-sections as on the lines 4-4 and 5--5 respectively of Fig. V2, looking down;

Fig. 6 is an elevation corresponding to a lower. portion of Figs; 1 and 2, as viewed from the right of Fig. 2 or from the rear of Fig. 1; andV Fig. 'l is a cross-section on the line 'I--l of Fig. 1*,v also looking down.

Referring to the drawing in more detail, and first to Figs. 1 and 2, the tool comprises an end block, casting or stock I having a laterally perpendicular nose or disk-cutter mounting 2Y and.V at right angles to the latter an annular seat 3 for a removablev threading die head 4 rotatablycarrying a threading die 5 preferably of the reversible ratchet type including a plurality of thread cut'- e ting elements 6. This main head or end member I,V when adapted for holding threading diemeans of the reversible ratchet type may also include a relatively Vshort boss I disposed substantially radially of the die head and housing a reversible spring-pressed dog or pawl, not shown, 'adapted to be adjusted as by the releasableplunger 8, for setting the threading die ratchet for operating in one or the opposite direction. The threader seat is adapted to receive interchangeable die. heads' with dies of different sizes; as for example. 1A, in. to 3A in. diameter for a given size of my tool, or 1 in. to 2 in. diameter for a larger tool size.

The block, main body or head element I further comprises a preferably integral elongated shank 9 including an upper squared portion I 0' and a lower cylindrical portion II externally threaded at its bottom or outer end as at I2, Fig. 2. This shank 9 is provided with an internally threaded central longitudinal bore I3, the threadstantially radial of the4 latter.

ing of which desirably is of a relatively low pitch. The shank 9 and its axial bore- I3^desirab1y but not necessarily are so arranged .relative tofthe. axis of the die head 4 that the bore I3gis sub- The internally threaded shank 9 is adapted to receive the correspondingly threaded upper or inner end I4 of-an elongated manipulatingorhandle member I5, illustrated as a tubular pipelike element, the lower or handle'portion proper of which is broken off on Figs. 1, 2 and 6 merely to conserve space upon the drawing., it being understood that -thishandle, bar or manipulating lever may be of any convenient` length. The exf' ternal threading along the upper or innerportion of this handlemember [5 is. ofsubstantial. extent downwardly from the extreme extent-,of the other, over a length in excess of thaty of the bore I3A of the shank 9, for a. purpose shortlyto be referred to. Y I

. rIhe main body; bloc-k, stock, or head element I, together with its shank llare herein .specially adapted and arranged to serve also as the supporting and guiding means for a slidableframe or carrier indicated as a whole-by the numeral, Y29. This. frame may be stamped, cast, forged or otherwise formed-.from suitable metal or other material. It comprises a supporting and guiding portion 2i which is preferably-of elongated tubular or channeled form adapting it to be received on andai. least partially to embrace the shank 9 of theihead orfbody I. As. herein shownthe upper part of theibore or channel ofA this frame portion 2Iis squared as at 22, Figs. 2 and- 4, similarly as` the upp'erfpart I0 of the shank 9- and issimilarly proportioned as the latter, for guided sliding reception upon it. vBelow the squared portion y22, the outer or lower part 23 ofv the supporting frame portion 2I is cylindrical, asis also the corresponding extent of the bore or channel, asl indicated at 24', Figs. 2 and-5.

y Referring still mainly to Fig. 2, the cylindrical lower portion of the bore or channel 24 of the frame portion 2I is of Vsomewhat larger diameter than the adjacent cylindrical` portion II of the shank 9. There is thus provided ybetween the two an elongated annular chamber 25.the upper or inner end of which is dened by a. shoulder 26 on the frame portion 2ll at the junction of the squared andcylindrical parts of its bore or channel.- This chamber-houses 'a fairlyheavy coil spring 2l surrounding `ther'cylindrical portion II of the shank 9 and bearing between said` shoulder 26 and the' end face of `a cap or collar 28 threaded ontothe threaded lower extremity I2, previously mentioned, of said shank portion II. This cap 28 has an outer diameter adapting it for reception Within the cylindrical channel 24 of the frame 2| without interference with the longitudinal sliding movement of the latter on and relative to the shank 9. At its lower end the cap or collar 28 is centrally apertured for free passage of the threaded portion I4 of the handle I5.

Thus it will be seen that the spring 21 normally urges the slidable carrier or frame 20 upwardly or inwardly, toward the outer end or head of the main body or stock I. The extent of movement of the carrier or frame 20 in said direction is l positively limited by lateral-.shoulders 29, 2 9 on the carrier I at opposite sides of thelatter, see

particularly Fig. 1, and which define the'inner. end of the squared portion of the .shank 9, these n shoulders preferably being inclined or non-peri pendicular to the axis of the shank 9, substantially as Yillustrated in Fig. 2.A The adjacent upperend faces ofthe'portionz'l of the'frame are laterally disposed along asimilar line'bf inclination, as at 29a, 29a, Figs.` 1 and 2,ypar'al'` leling'the shoulders 29 of the carrier and against which, under theinuence of the 4*spring 21, they normally haveKV accurate vabutting-contact. The inclination of the shoulders-29 and thevend faces 29a of the vframe portion 2| vailord somewhat of a lateral camming action `lnetween 'the two` whereby side-play between the relatively slidable parts is takenup; i A* f In addition tothe describedl supporting andv guiding portion 2| of the carrier or frame 20, the latter is provided, herein integrally, with a laterally projecting upperportion indicated as'a whole by the numeral 3,0.l This'projectingl portionof theframeZll is recessed or bifurcated to provide a pair of spaced wall membersor flanges 3|, 3|, Figs. 1, 2 and 4; spaced apart by a recess or chamber 32. Within this chamberfis'mo'unted holding means for a plurality of rotary elements for pipe-cuttingpurposes. Said means as herein illustrated comprises a holder or cage including a pairV of spaced plates 373, V34, centrally united by a hollow tubular connection or sleeve 35,'see particularly Fig. 3.1 These holder plates desirably are of a somewhat resilient sheet materiahenabling them at times to be sprung outwardly in a manner as indicated at the lower portion of Fig. 3, for the purposes of removing and installing orreplacing therotaryy elements to be referred to, one`suitab`le'f material being' a hardenedl sheet steel" of fairly light* gauge. The holderfpla'tes 33,' 34 'may -be variously rshaped and as hereinhsho'wn are (gluatrefoil,A presenting four arms, as indicated at 36,' 33, etc. vEach of these arms is 'centrallyl apertured toiprovdarotary bearing support for the rotary. element's'to bedescribed.' V v-l l" Yi' Y .-1

Said rotary elementsA herein removably -associated with the described spider-like cage or holder comprise apair of rollers 40 having ce'ntrally apertured projecting hubs 4I Y adapted for freely rotatable reception in' thebearin'g recesses of two adjacent varms 36'o'f the cage. In the position of the latter as illustrated in Figs.l 1 to 3, this pairV of 'rollers '40 is uppermost. The

other two arms 36 of the cage are adaptedsimilarly to receive a pair of rotary disk cutter elements each comprising a disk or 'cutter portion proper 42, a cylindrical centrally apertured body 43 and their hubs'or bearings 44. By reference particularly to Fig. 3,1-it will be seen that these rotary cutter elements 43, and similarly also the rollers 40,'may're'adily be removed or inserted with reference to the supporting plates 34 of the cage or holder, Vmerely by springing the plate arms slightly apart, after demounting the collar unit from the tool, while in the assembled condition of the cage or holder unit the plurality of rotary elements including the adjoining pair of rollers 40 and the symmetrically disposed pair of disk cutters 42 are each freely rotatable upon their respective axes.

-Y vA further -advantage inqthev conjoint single or plural-disk cutter mechanism, and I.particularly under the provision for ready removal of any of the cutter disks, is that in the case of breakage ofthe cutter of the stock or head I under circumstances Where an extra replacement disk is Anot immediately at hand, the operator may tem- :porarily rob one cutter from the holder and install it upon Vthe carrier head I.

Thus he is assured of having available at all times at least a single-disk cutter arrangement. Such procedure may be repeated, byutiliz'ing a second cutter from. the rotatively 'adjustable cagev orholder,Y in case'of a'further breakage of the cutter of the single-disk position. 'Ihe described cage or holder unit as a whole is removably mounted in the chamber or recess 32 of the carrie'ror frame 20,- in a manner permitting the holderat desired times to be rotated about the axis of 'its central sleeveV 35. For so mounting the holder, the lateral flanges 3| of the slidable frame 20 are provided with aligned apertures 3 Ia for'the reception of a removable-pivot pin 45, Figs. 1, 2 and 4,' which is adapted lto pass through' and rotatably receive the central holder sleeve 35.-

Referring again to the head or stock elementl of the tool as "a whole, the lateral nose 2 of.A the latter, previously referred to, has lformed in its underface a recess `4'| for the' reception of 'a rotaryu disk cutter 48`which may be identical or substantially' so to the rotary cutter elements 42 of the described holder, the Walls of the recess- 41 being themselves recessed at their inner pposite faces to accommodate thecutter hub such as 44 ofFig`.`3. Said" walls alsoare aperturd in lateral alignment to receive a removable'pivot pin 49 of a length to extend through said walls and through' the central aperture of the 'disk received between them' thereby removably to support the cutter 48 rotatably -in operative positio'm y By reference particularly to Fig. 2, it will be noted'fth'a't theaxis of the sleeve bearing 35 of the roll and cutter cage is so disposed relative to the axis of the upper cutter disk 48 and with the roll and cutter holderfandits supporting frame 20 -in their'upper or innermost position as represented in Figs.' 1 and 2, the axis of said upper cutter 48 and the axes of the two rotary elements then uppermost in the holder are disposed at the 'points of an isosceles and herein a substantially equilateral triangle. Accordingly the two rotary elements of the pair 40 or the pair 42, whichever is disposed in uppermost position at the given time, are equally spaced from and symmetrically disposed relative to the singular or upper cutter disk'48, thus adapting them for cooperative cutting effort upon a pipe or the like inserted centrally between them.

From the foregoing it will be seen that I have herein provided selectively and rotatively'adjustpair of rolls, such as MI, vor a plural and herein three-disk cutter wherein the previous single disk and the pair of cutter disks of the adjustable holder are the active cutting means. v"It-also" will be particularly noted that the recss of the s'lidable frame or carrier element ofthe tool is proportioned and arranged to accommodate the rotary adjustingmovement of the cage or holder unit, the inner wall of said recess' being arcuately'grooved as for example at 32a;

Fig. 2, if necessary for clearance. I In Figs. 1 and 2, and correspondingly in Fig. 4,: the cutter disk and roll holder is illustrated-in its adjusted position for operation of-the' tool' as a single disk cutter. *The pair of-rol1s 40 accordingly are uppermost. For 'retainingf'the holder in the selected position of adjustment suitable lock means is provided; l-'iereincompris-l ing a pair of self-lockingfpins orvstops |),r 5ll,4

Figs. 1 and 2. 'Ihese'are removably-insertedv through appropriately disposed aligned rece'iv-l Fig. 1, in the respective ing apertures 5|, 5|, anges 3| of the slidable carrier or frame 20. With these lock pins 50 installed, the roll and disk holder is rmly held against bodily turning' about the axis of its bearing sleeve 35. The single disk and opposed roll pair arrangement is generally preferable for use under circumstances where the tool as a Whole may be swung completely about the pipe or bar to be cut.

Under other circumstances, such as for pipes ing die head cooperatively embodied in combina tion with the common carrier and manipulating handle element. v

To shift as between the single disk and rollj combination of Figs. 1, 2 and 4, and the three# disk arrangement, it isV necessaryme'rely to with"-A draw the lock pins 5!! and to rotate the cage or` holder bodily upon the axis of its sleeve-35 until' the pair of disk cutters 5.2 are turned upv into the uppermost position, adjacent thcfsingle 'disk ,43,1

with their central apertures respectively'in'line with the locking lapertures 5| of the flanges The lock pins 5B, of which in some instances but one need be employed, are` then reinserted,`

whereupon the tool is immediately ready forv operation as a three-disk cutter. j With an exterior cutter such as here concerned,

it will be understood that in order Lieblingt the tool into operative position relative to the' pipe or other work, it is rst necessaryto open or separate the rotary elements, whether, these at the given time consist of the single cutterv and opposed rolls or a plurality of cutters.. so asI to bring them into surrounding relation with the work and to enter the latter into the space de-` ned between the adjacent portions of the peri-pheries of the several rotary'elements. Customarily, in the usual single disk cutting'tool and yalso, in the separate tool having a plurality of-cutters, it is necessary to back off a threaded member which carries one or 'more of the rotary elements;

towprovide such .opening for the pipe', and'fthenvf again to .t'urn back the. threaded member sof as to closetheA vrotary elements onto the work." Thisl generally involves more or less trialv and error and is cumbersome .and ktime-consuming.I In accordance with my invention, however, it Will be seen thatsuch operationof the rotary elements-whether these at the given time are the single disk and roll pair or the. plurality of roll disks, is. easily and quickly accomplished merely by s-lidalo'ly retracting the entire body or frame Zai-together with the roll and disk holder carried byrit; againstthe Vpressure of the spring 21,

sui'ciently to aord entrance for the work,'upon` subsequent'irelease'of the frame 20 the springl immediately forces the latter back or up intoV abutting engagement of the shoulders 28e-ofi thecarrier and the end faces 29a of the' holder frame. It will further be `observed that Ysaid shoulders or abutment formations are so calculated and'arranged relative to the location of` the'roll and disk holder and of the single disk cutter upon'fthe head or stock that upon such automatic return ofthe frame the selected' rotary elements are accurately inter-positioned in cooperative contacting relation with the work. 'In' this connection, a further important ad# vantage of lmy improved tool resides in its capacity for provision of indicating meansV whereby the pipe-cutting elementsy of the tool may be definitely'set for operation upon pipe or other cylindrical work of a given diameter, such for example as 1/3, Vi, 1/2, 5/8, 3A; in., etc. (inside diameter). Thus when a number of cutting operations are to be performed upon the same size` of work the tool may be set to the given sizeyasfor example 1A; in. pipe (inside diameter) as assumed in'Figs. 1 and 2 or 3A in. as assumed in Fig. 6. Or the setting may readily otherwise be adjusted at any time, thus facilitating quick `lifting as between cutting operations uponwork of different sizes.

Referring now more particularly to Figs. 1,1 2 and 6, means Ais provided for variably determining 'and' limiting the extent of .downward or outward-movement of the roll andY disk frame 20 against the compression of the spring 21. For thisA purpose I have herein provided a nut-like fitting `orcuppe'd stop and finger piece 55 xedl'y. associated with the manipulating element 'or handle f5.' As illustrated this fitting 55 has a central aperture which is internally threaded in conformity with the threaded portion I4V of the handle. In assembling the tool', the fitting 55' isffirst installed upon the handle'l5, prior to threading of the latter into the shank 9. Thev tting is turned completely home to the extreme lower end of the threaded portion I4 sol as toflx itsecurely upon the latter.

' This fitting 55 comprises a centrally recessed or cuppedhub end 56 the recess 5`| of which is cylindrical and of a diameter to receive with a guided sliding t the lower cylindrical portion 23 of the frame 20. The bottom wallY 58 0f said recess'l` constitutes an abutment stop for 'the' lower end of the frame portion 23, thereby limiting and positively deiining the extent to which the -frame with its disk and roll holder may beV retracted. Y

A setting index desirably is provided as between the fittingand the frame 20, for setting the tool in the above described manner for the different sizes of work within the capacity of the giveri tool. HereinA for the purpose, I employfthe upper edge 59' or the fitting 55, Fig. 6, as an index' or pointer for 'cooperation with a scale 60 stamped or otherwise marked at any convenient lower por-v tion of the frame member 23, asV for example at the right in Fig.- 2, which area is seen foremost in the position of Fig. 6. In the latter iigure a setting is represented as for cutting workof 3A in. size. To eiect such setting the handle member I5 is turned in andrelative to its support# ing shank 9, the frame 20remaining in its lower-i most position as in Fig. 2, until the desired unitV or marking of the scale 60 is brought opposite the index line 59. In Figs. l and 2 the tool is represented as set for one of the smaller worksizes, the frame 20 being disposed for downwardly opening retraction only 'by the extent represented by the distance between the lower end of the frame member 23 and the opposite bottom wall 58 ofthe fitting 55.- In proceeding fromsuch setting of Figs. 1 and 2 to that as shown byway of example in Fig, 6the handle memberv I5 accordingly is backed out from the'shank 9 until the marker or edge 59 of the iitting 55 is brought down to expose or come opposite the 3/11 mark of the scale 60. It will be understood the tool may be made in different sizes or with different ranges for a given tool, such for example as a junior size having a range of say 1A; to 'TA inch substantially as illustrated, and other sizes for work ranging through the larger diameters. Under any given adjusted setting, such as that at the it mark as represented in Fig. 6, the pipe cutter element of the tool, whether the disk and roll or the plural disk arrangement is to be used at the time, is automatically readied for a cutting operation upon a Vpipe or like work of the diameter indicated. That is, under the 3A' setting the roll and disk holder frame'20 may be retracted to the extent necessary to open the rotary elements for ready admission of the work of ,3/1, in. size, and upon release of the retracted frame the latter is automatically returned by the spring so as to close the rotary elements into proper operative contact with the work.

For additional easeinretracting the frame 20 against the spring, it may be provided `with finger or' hand engaging means, such for vexample as the protuberance or raised surface 20a, Fig.2.

Also'manipulation of the handle l5' and fitting fixed thereon may be facilitated, aswhen making a size setting 'as above described, as by the provision of one or more longitudinal wing-like formations or ribs 55a, of which three are hereinV provided symmetrically distributed around the fitting; see particularly Fig. 7. Ihese ribs may have knurled or roughened outer surfaces for gripping purposes, 'as seen at 'the lower portion of-Fig.1.v m Various other advantages of the compound tool of the invention will be evident in addition to those of convenience and time-saving through accomplishing the several different operations with the one tool. These include, for example, thesubstantial savings in materials, parts and manufacturing cost through the provision for selective adjustmentas between single disk and roll, and plural cutter disk arrangement in associati'on with a common supporting body, and through the utilization of a common supporting head stock or body and handle element for both the single disk cutter and the threading die and wherein the shank of such head stock serves at once for the attachment of the one handle element and for the guided slidable support of the pluraldisk and roll holder frame for cooperation with the single disk cutter of the conjoint diskcutter and. threading-die supporting means or head stock.
